To all whom it may concern:

Beit known that 1, JOHN Or'ro JUnIUs Born, a citizen of the UnitedStates, residlng at Mora, in the county of Kanabec and State ofMinnesota, have invented certain new and useful Improvements inVentilators, of which the following is a specification.

This invention relates to ventilators and more, particularly to aventilator box adapted to be readily inserted in a suitable opening, forinstance, in the wall of a barn, the said box being of such constructionas to prevent rain, sleet, or snow from being confined in the same. i

The primary object of the invention resides in the construction of anovel and improved ventilator box adapted to be positioned whereverdesired in a building structure including provision for preventing theaccumulation of dust, dirt and other foreign matter which might lodge inthe bottom of the box.

Another and very important object of the invention resides in theconstruction of an open screened ventilator box capable )of beinginstalled and adapted for use in wooden as well as concrete structures,and particularly designed for installation in the walls of barns, andthe like, the bottom of the screen being secured in spaced relation fromthe rounded bottom of the ventilator box so as to permit the cleaning ofthe interior of the box of any foreign matter that might accidentallyaccumulate therein.

Another and very important object of the invention is the provision of aventilator box designed for use and adapted to be installed in variouspositions where desired, and one in which the parts are extremely simplein construction, easily assembled, rigid and durable, highly efiicientin operation, practical and capable of being manu- 'liactured at a verylow cost whereby its commercial possibilities are greatly enhanced.

With. these objects in view and others which will be manifest andsuggested. as the purpose and nature of my invention are revealed in thefollowing specification and drawing wherein I have shown a preferredembodiment thereof,

Figure 1 is a front view of the device.

Fig. 2 is a vertical sectional view therethrough, and,

Fig. 3 is a sectional view taken on the line 33 of Fig. 2.

Referring now to the drawings wherein like reference charactersdesignate corresponding parts throughout the several views, 5 designatesa portion of a wall of a building structure which is provided with anopening therein for receiving the ventilator box shown in detail by Fig.2 of the draw ing and which will now be described in detail.

The end walls 5 are preferably provided with an L-shaped metallic sill6, which reter into the interior of the box as is readily understood.The lower end of the screen 12 is preferably secured to a cross piece 13positioned in spaced relation with and in close proximity to the curvedbottom 7, of the ventilator box, so as to provide a space 14; whichpermits the cleaning of the said ventilator box by the insertion of anyfiat instrument to remove the accumulated matter. In other words, byreason of this construction, any matter falling within the curved bottomof the ventilator box may be removed from the interior or exterior ofthe same with facility and ease and at all times maintain the ventilatorin a clean condition. The opening 14l between the screen and the frameis not suificiently large enough to permit the entrance of any birds ormice into the ventilator, which is the common 0bjection to other formsof similar devices now in use.

The construction as above described, is extremely simple in its generalarrangement since the same may be easily installed without anyparticular labor or skill in an opening in the wall of a buildingstructure and since the device is such as lends itself to bemanufactured in various shapes, sizes and styles to suit the needs andoccasions as required, the ventilator box is extremely practical anduseful for its intended purposes.

In the accompanying drawings, T have illustrated'my invention embodiedin one form by way of example, and which in practice has been found tobe highly satisfactory in obtz-iining the desired results It. Will beobby those skilled inthe art Without departing fromthe spirit and scopeof the invention. It is furthermore understood that the invention is notnecessarily limited or restricted to the precise elements shown exceptin so far as such limitations are specified in the subject matter beingclaimed.

Havingshown and described my invention, What I new claim as new anddesire to secure by Letters Patent of the U. S. is:-- I

1. A ventilator comprising a hood open at its front and top and having aclown- Wardly and outwardly curved bottom, said hood adapted to beseated Within the opening of a Wall, and a foraminous element securedinthe front portion of? said hood v I i ra-1,070

foreign matter from the exterior or interior of the hood. 7 I

2. A ventilator comprising a hood open at lts tront and top and having acurved bottom adapted to be seated Within the openings of a wall andprojecting rearwardly therefrom, and a cross piece fixedly securedWithin said hood inc-lose proximity to the bottom thereof, saidcrossplecespace'd from said bottom, and a foraininous shield arranged atthe front portion of said hood connectedtothe cross piece and furtherhaving portions thereof engaged by the sides of the hood for securingsaid portions in position.

In testimony hereto.
